Just want to list out the 3 tips that really helped with GPS locks (for me):
1. d/l "GPS Status" and aGPS reset/download (this thread);
http://forum.xda-developers.com/showthread.php?p=11872531
Thanks to neh4pres!
2. use "GPS Status" d/l to recalibrate magnetic compass;

Thanks to j32driver!
3. modify /etc/gps.conf entry (requires root/temp root) changing NTP_SERVER=north-america.pool.ntp.org to NTP_SERVER=us.pool.ntp.org.

Thanks to calebv2!
Sadly, these fixes will not fix issues related to bad satellite coverage/visibility/interference. And won't fix EC09 fried SD cards, either.

Thanks for all the links and help here. My GPS has always been sub par. While it will still not lock on when I'm in my living room, it gives me fairly accurate locks when outside.

Glad to see this helped people.. For really stubborn gps locks, follow my original instructions after a fresh boot.

Bingo. I had updated to ED01 and was getting nuthin' at all from the GPS. Did the reset/update AGPS, adjusted the NTP server, and within 5 seconds or so had 8+ satellites and 14-foot accuracy. Sweet.

I had tried all listed suggestions above and still could not get a lock without a 2+ minute delay (and only using GPS Status could i finally get a lock)
I updated my radio to EC09 last night and Instant GPS!!
So excited about that I can even pull GPS without cell signal which i have never been able to do before.

Editing the GPS.conf work perfectly. I went from no locks to locking in 2-3 seconds.

as soon as vzw comes out with a dual core lte that i like, i will dump my fassy bc of the gps lock issue. i have tried every "fix" i could find since i got the phone over 1 year ago, and still have issues. whats odd is that i can have a perfect lock and use gps to arrive at a destination, but when i leave the building cant reaquire! sometimes a battery pull solves the problem, sometimes just 20+ min of waiting. uggg!

Helped me !!!
took just 1 minute in total LOL.
god bless mate .

I now use "gps aids" from market.. It seems to work little better.. Next time im at a computer I'll update op

[Q] GPS under-utilization of GLONASS satelites with stock rom

It is apparent that when looking at the signals, GLONASS satelites are often ignored even though they are coming in at the same or better strength than US-GPS ones.
Can the code be tweaked?
Who knows about the code and what is needed to hack it?

I had an issue when I got the phone where it completely ignored GLONASS. You can try two things:
1. From the hidden menu (3845#*80x*#, where x is the mark of your phone's model), go to GNSS Test, press Menu, choose Delete Aiding Data, then Menu again and START GPS. Do this while connected to a wifi or mobile network, let the phone connect to satellites. When it does, exit the service menu and see if it will connect to GLONASS then.
2. Download GPS Test from Play Store, go to Settings and clear or update A-GPS data, then try again.

Thanks for the tips. I upgraded to Kit Kat then tried all the above.
Did #1 - It did get a lock (Time to first Fix) in 4 minutes. That was pretty good and it was clear sky.
Did #2 - Still very poor GLONASS utilization. Only locked on 1 GLONASS out of 4 available (all strong signals 20db avg. - same avg as US-GPS ones) But it locked on 8 or 9 US-GPS (100% of available).
LG has authorized me to take it to repair centre and I am hopeful they can fix it. From what some others wrote, they might not get a lock but someone else with same G2 will, even in less ideal conditions. So maybe there is some sort of hardware problem that is causing the avg 20db to 30 db reception even under clear skies. Mine had good contacts under the cover so I am thinking that maybe the GPS unit module come in varying quality and maybe even the patch antenna is subject to quality issues.
Who knows. Still a fact that my 4 year old Blackberry gets better GPS fix than this LG G2.
Crossing my fingers and toes that they can fix it.

Found this explanation of how the processor chooses between GLONASS and US-GPS:
http://www.qualcomm.com/media/blog/2011/12/15/gps-and-glonass-dual-core-location-your-phone
The Snapdragon processor automatically knows when to power on the GLONASS service, and when to leave it off. GLONASS will only engage when an adequate GPS signal can’t be found. This extends battery life while providing the best navigation experience possible

Obviously something is going wrong since it appears that it is not switching reliably to use GLONASS when it needs to find a fix.

The phone is back from the shop. They replaced the mainboard. The GPS now works 1,000 % better than before.
=== Before ===
First lock with no aiding data, only 1/2 sky available: 245 seconds.
Second lock: 10 - 14 seconds.
Fix while in office 2 metres from big window: never
=== After ===
First lock with no aiding data, on;y 1/2 sky available: 74 seconds.
Second lock: 1.4 seconds.
Fix while in office 2 metres from big window: 2.4 seconds to fix
Bada Boom Bada Bing!
Glonass is showing, but after a good fix, it switches to just GPS. Fine with me, because it at least show 2 or 3 GLONASS while getting the fix and a short time thereafter.
So, if your GPS sucks, maybe you should try getting it repaired.
edit: of course, we will have to see what it does on a cloudy day or while driving. But still, the way the GPS found and fixed the location was waaay faster than before and I never got a fix at home inside 2 meters from the window before - never!

GPS issue can't lock a signal at all or really slow an inaccurate

I've read a lot about people having issues in KitKat 4.4.2 and I'm having the same. Which is the GPS not locking a location. I've tried many things like apps such as GPS Fix and even flushable zips. I don't know what caused the problem but I have gone back to stock and still nothing. As of right now I'm running PA Beta 3 along with the latest Franco Kernel #206. Please I'm hoping someone has a fix

If you haven't already, try the "GPS Status" app.
There you can hit the menu button, press "Manage A-GPS State" and reset the AGPS cache. Then go to "Manage A-GPS State" again and download new AGPS data in place of the cache you deleted. Make sure you have a working data/wifi connection when you do this.
Note the number of sats fixed (they show up as visual green bars, you can also find the number on the left side of the "/"). You generally need more than 5 in order to get a steady lock, though that admittedly is tough if you have any overhead obstacles. This app will also tell you the "time to fix" so you'll know if it takes too long.
If you want, you can set it up to have a constant notification whenever the GPS is in use, and that way you could pull down the notifications bar while you're on the Maps app, then hit the "GPS Status" notification to pull out the app and get you a faster lock. At that point you just press the back button to return to Maps, whence it has fixed a location for you, and voila! You can even calibrate the compass.
Also, another thing you could do is set it to automatically download new AGPS data for every given length of time. I personally set it to every 6 hrs; that way if the GPS starts acting up, you'll automatically get new AGPS data within the day to help it lock faster.
Hope this helps!

How to fix GPS not finding location issue?

I've tried TopNTP though GPS still won't find my location and if it does it takes over 10 mins.
I've just rooted my phone today so hoping I can get this fixed.

Yes I have been searching and most of them lead to TopNTP

Assuming your location is on/high accuracy and the map program you are using has permission to use gps, search for NV factory reset. You need to enter service mode, *#197328640#, and then get to NV rebuild option which is kind of convoluted, so best to follow instructions to the letter in this forums. I think another way to get there is using *#0011# but also tricky by hitting menu, entering q, then 0000, then going through the menus, which I don't remember offhand. That should rebuild your NV and fix the GPS.
I have not tried it since my GPS works fine but it seems to help others with issues.

GPS FIX
I was about to drive from Texas to Florida and my gps was not working on stock firmware .
I found solution and now I get 8 to 10 sats inside my house within SECONDS !!
do this on ANY ROM :
On you dialer type in this *#0011#
Press menu key > press back ( not back arrow but the WORD back )
Press menu key > press key input > Q
Press menu key > press key input > 0000 ( zeros )
Wait for a few seconds and the screen options will change
Press on UMTS
Press on Common
Press on NV Rebuild
Press on NV Rebuild ( yes again )
Press on System, Protocol, GPS, IMS

Maybe you already did this - if so, apologies. TopNTP will not install automatically on the Note 3, the gps. config file must be pushed manually to system/etc with rw-r-r permissions. If you don't install it like this the stock gps. config file won't be overwritten and the stock file is unchanged.

I've been having this issue on Note3 (9005 International Version) since upgrading to KitKat.
Before KitKat, it would lock in matter of seconds.
I tried everything. I mean, I even changed ROM's.
The *#0011# solution didn't really work. But, it kinda changed something.
Before, it would get stuck on 4-5 satellites. Not it gets stuck on 7-9. And, sometimes it gets a lock. A little, little better than before.
It's strange with my phone that it wouldn't lock only on my home country, SouthEastern Europe.
It would lock on neighbouring countries in matter of seconds. I get a lock in other parts of Europe as well.
In States, it takes 4-5 seconds to get a lock. In all these countries, I never loose a lock or nothing during navigation.
I get back home, I don't get a lock.
And it's frustrating . . .

Searching using GPS... issue (Samsung Note 3)

Hello, I'm new to this forum and I want to know is there anyway to fix my Samsung note 3 GPS? I'm having trouble with my GPS that constantly keeps on showing "Searching using GPS". For some reason it doesn't lock my GPS to "Location is set", The Specs on my Phone is Samsung note 3 (SM-N9005), Unlocked, Region from Greece, and my android version is Lollipop. I did the most following method from researching my Note 3 issues lately and still no solution to get it fix. The result on my GPS Status&tools shows the result that my GPS shows fix 0/17 Sats.
Heres the list of what I've done.
1. opening up the back of my phone unplug my GPS and re-plug it to the mainboard
2.tighten the screws on the backside to get the 2 pins to be contacted
3.updated my phone to lollipop and I still get the same result with no GPS fixes
4.location has been set to high accuracy and already set a google location history checked.
5.Rooted my phone to fix the GPS, still no solution.
6.Disabled the mock location on developer menu.
7.Downloaded GPS Status& Tools and reset my A-GPS or download.
8.Same issue along with Kitkat update.
9.Open Google Maps as a background app
10. Updated google play services and still doesn't work.
That's all I've done. Any solution to get this fix? My carrier is T-mobile. I can still text, call, use mobile data, other than GPS.
P.S. I've been playing Pokemon GO with it. Every time I drive to a main event, my character doesn't move all it does is jump to a different street.
Thank you.

You may need to be on a stock ROM for this to work, but this is what fixed it for my N900W8 (gleaned from this thread):
1. Open the Dialer.
2. Enter *#0011# (hit the call button if nothing happens automatically)
3. Menu key -> "Back"
4. Menu key -> "Key input" -> enter Q
5. Menu key -> "Key input" -> enter 0000
Now, if you have an "UMTS" option:
6a. Tap "UMTS"
7a. Tap "NV Rebuild"
8a. Tap "NV Rebuild" again
9a. Tap "System, Protocol, GPS, IMS"
10a. Wait a minute, then reboot
If you DON'T have an UMTS option:
6b. Tap "UE settings and info"
7b. Tap "SETTING"
8b. Tap "SYSTEM"
9b. Tap "NV REBUILD"
10b. Tap "PROTOCOL, GPS, IMS"
11b. Wait a minute, then reboot
After that, GPS should work again! Note: If you're not on a stock ROM and that doesn't work, make a TWRP backup, then wipe everything but internal storage and SD, install a stock ROM (preferably not an Odin one that will overwrite recovery), follow that guide, then restore your backup but DO NOT restore EFS or Modem. Worked for me.

Reads like hardware or kernel as GPS is a kernel function .

Just recently followed your method and its not locking GPS location to set by. I am in Stock ROM, its just that I don't want to take risk of rooting my phone. Is it possible to root the phone and use the app called "Faster GPS" just to get a better GPS locking?

Strange, then. Try downloading GPS Locker, it'll show you a chart of signal strengths for each satellite. Do you get any signal to any satellite? The problem I had that my method fixed was that it was seeing the satellites, and getting green bars, but not locking on to them. If you're not getting any bars, you might need to take it apart and check on those pins again - they should be bent upward so they make good contact. Faster GPS is also good for speeding up, but I don't think it'll fix it if something's broken.

Try using FasterGPS, but if that doesn't work, you may need to check the antenna again. If you're outside with a clear view of the sky and you're getting that poor of a signal, it seems like the hardware could be your problem.

In case you're using metal case, remove it.

Well... I tried FasterGPS today and well... I still cannot get a locked Gps signal. *sigh* I guess its just my hardware then... Well thank you for the help Jaitsu. No worry, I can live without the GPS as long I can use my phone as a hotspot for my other GPS devices. Will replacing the mainboard resolved everything?

Hey guys, just posted in rom section, but i will ask here also.
I have same problem with GPS. My phone finds like 25 sattelites but doasen't lock for a very long time (if it do it locks to 2 MAX 3 sattelites)
I tryed everything, screweing the screws open the back and put the antena out, i tryed with different modems, latest i flashed it's POK2...
When runned on 6.0.1 phrorensis 1.0v rom i did as i wote before, and the GPS worked great, realy in a coupple of sec. it locked 1'0-13 satelites... but than suddenly it stoped. I don't know its a rom problem, it's my phone... I also tryed variuous Kernels... always the same
So mate Try lo tie the screws, try, to open the pack and "put out" the antena "pins" if that doasent work, try to upgrade ur modem and try different kernel.
So try this ( the video is for s3 but i's simmilar for n3 )
https://www.youtube.com/watch?v=9ZKlsQF4LE8
if not try flashing new modem
https://idlekernel.com/flash-tools/firmware/
POK2. the newest is hlte_SM-N9005ZS/ ( well for my n9005)

At least you're seeing satellites... Which is more than I've got.
The latest Google Play Services has completely destroyed my GPS. It won't detect any satellites at all, and Google Play keeps scanning for Location even when every possible location setting is disabled.
Only way I can get satellites in view at all is to reboot with GPS off, then ONLY turn on the GPS. The second I select High Accuracy or Power Saving, it won't detect anything until I reboot. The seconds I open the Play Store, with or without location on, GPS is dead.
Thought it was my device dying (well, it is 3 years old), but my NotePro is doing the exact same thing since the exact same update. (It also won't detect 4G anymore, which, thankfully, isn't plaguing my Note 3....)

GPS problems - i solved it 4 me
So facing GPS problems?
I was facing it to, i tryed various things to fix it, i'did evrything i wrote down here
- Check ur csc version if it's not right you need to change it
i used https://play.google.com/store/apps/d...honeinfo&hl=sl
- try this app "FasterGPS" and insert ur location / country NEED REBOOT
https://play.google.com/store/apps/d...=org.fastergps
-Try to update modem and bootloader
https://idlekernel.com/flash-tools/firmware/
-Try different Kernels , here is the link to DL kernels (now im using Lss3.3
https://www.androidfilehost.com/?w=files&flid=34872
- if still doasent work try to open ur phone and fix the "antenas"
https://www.youtube.com/watch?v=3t9vztad58g
I did all of these things than I let the GPS turned on. It locked the sattelites now its working like a charm it locks the sattelites in a few seconds.

Okay... I've done using fasterGPS and reboot to the exact location where I'm at, already opened the Antena, but now updating the modem and boatloader for my models seems to be lost. I haven't update it yet, but which SM-n9005 do I have to update with? Turns out mine is N9005XXUGB06 for the modem or bootloader. Btw, updating Kernel from Dark lord... Which version should I go for? Because I want to stay at official lollipop update instead of rooting it along with the update. I was thinking about maybe 1.6 - 5.1?
